nected along: one margins'rbyxthe gusseti'ZI'fomxed by strips 5 and 1.It will be seen that each of strips 5 and I forms one panel of thegusset and that strips 5 and I are seamed together at i3 and are seamedto the strips 3 and 9 at l I and l 5, respectively, along the lineswhere the gusset folds. To form covers of this invention from the web W;the web is segmented into cover lengths by cutting it transversely onlines (Fig. 2) spaced at intervals corresponding to cover lengths, Then,each cover length is seamed at its two sides transverse to the gussetformed by the cutting.

Figs. 4 and 5 illustrate the resultant cover. It will be seen that thecover consists of two superposed fiat rectangular sheets and 9a, whichare segments of the original strips 3 and 9, the edges of the sheetsbeing substantially coincident. The sheets are joined together along twoopposite sides of the cover by closures 2i and along a third side by agusset 2311, which is a segment of the original gusset 23. This gussetwhen folded lies flat between the superposed sheets 3a and 9a, and itsends are caught in the seams 21. The latter, as illustrated, are formedby folding tapes 29, such as paper tapes, around the sides of the sheetsand sewing a seam 31 through the tapes and side margins of the sheets.Other suitable seams may be used. The cover is open along its fourthside at 33. The gusset consists of superposed separate flat strips 5aand la, which are segments of the original continuous flat strips 5 andI, seamed together fiatwise by adhesive at 13a and to the sheets 3a and9a at Ha and 15a, respectively, along the lines where the gusset folds..Fig. 6 illustrates a modification wherein the gusset has four panelsinstead of two. The outer sheets are the same as in the Fig. 4 form andare again designated 3a and 9a. The panels of the gusset are designated35, 31, 39 and 4|. Panels 35 and 3'! are seamed together along theirinner margin by adhesive 43. Panels 31' and 38 areseamed together alongtheir outer margin by adhesive 45. Panels 39 and ll are seamed togetheralong their inner margin by adhesive El. Panel 35 is seamed along itsouter margin to the margin of sheet 3d at 49, and panel M is seamedalong its outer margin to the margin of sheet 9a at 5|. It will beunderstood that the Fig. 6 cover is otherwise made like the Fig. 4cover, and that in its manufacture, four gusset strips are sandwiched inbetween outer strips 3 and 9 of two as in Fig. 1. It will be understoodthat within reasonable limits, the gusset may have any even number ofpanels greater than four.

. In view of the above, it will be seen that the several objects of theinvention are achieved and other advantageous results attained.

As many changes could be made in theabove constructions and. methodswithout departing from the scope of the invention, it is intended thatall matter contained in the above description or shown in theaccompanying drawings shall be interpreted as illustrative and not in alimiting sense.

We claim:

1. A cover particularly for use to cover relatively large objects, suchas large articles of furniture, comprising two superposed fiatrectangular sheets of flexible sheet material having their edgessubstantially coincident, said sheets being seamed together along twoopposite sides of the cover and joined along a third side by a gussetadapted when folded to lie flat between the sheets,

the ends of the gusset being caught in said seams,

the cover being open along its fourth side, the gusset consisting ofsuperposed separate individinstead ual flat strips of flexible sheetmaterial of width less than the dimension of the sheets transverse tothe gusset, said strips being seamed together and to the sheets flatwisealong the lines where the gusset folds.

2. A cover particularly for use to cover relatively large objects, suchas large articles of furniture, comprising two superposed fiatrectangular sheets of flexible sheet material having their edgessubstantially coincident, said sheets being seamed together along twoopposite sides of the cover and joined along a third side by agussetadapted when folded to lie flat between the sheets, the ends of thegusset being caught in said seams, the cover being open along its fourthside, the gusset consisting of superposed separate individual flatstrips of flexible sheet material each forming one panel of the gusset,the strips being of a width less than the dimension of the sheetstransverse to the gusset, and being seamed together and to the sheetsfiatwise along the lines where the gusset folds by adhesive between theopposed marginal faces of the respective strips and sheets.

3. A cover particularly for use to cover relatively large objects, suchas large articles of furniture, comprising two superposed flat papersheets having their edges substantially coincident, said sheets beingseamed together along two opposite sides of the cover and joined along athird side by a gusset adapted when folded to lie fiat between thesheets, the ends of the gusset being caught in said seams, the coverbeing open along its fourth side, the gusset con-v sisting of two flatpaper strips narrower than the sheets, each one extending the fulllength of the gusset and forming a panel of the gusset. the strips beingsuperposed and seamed together fiatwise along their inner margin at theinner fold of the gusset and seamed flatwise to the margins of therespective sheets at said third side of the cover.

4. A cover particularly for use to cover relatively large objects, suchas large articles of furniture, comprising two superposed flatrectangular paper sheets having their edges substantially coincident,said sheets being joined together along two opposite sides of the coverby seams each comprising a paper tape folded around the sides and asewed seam stitched through the tape, and joined along a third side by agusset adapted when folded to lie flat between the sheets, the gussetconsisting of two fiat paper strips narrower than the sheets, each oneforming a panel of the gusset, the strips being superposed and seamedtogether fiatwise along their inner margin at the inner fold of thegusset and seamed flatwise to the margins of the respective outer sheetsat said third side of the cover at the outer folds of the gusset byadhesive between the opposed marginal faces of the respective strips andsheets.

5. The method of making paper covers particularly for use to coverrelatively large objects, such as large articles of furniture,comprising the steps of withdrawing two relatively wide continuous websof paper from individual supplies thereof and causing them to travel insuperposed and aligned but spaced apart relation to a combming locationwhere they come together, withdrawing an even-numbered plurality ofpaper strips all of the same width and narrower than the webs fromindividual supplies thereof and causing them to travel between the websin superposed and aligned spaced relation with respect to one another,said strips coming together with one another and with said webs at saidcombining location with the innermost edges of the strips aligned withone another and with the outermost edges of the strips aligned with oneanother and also with two aligned edges of the webs, applying adhesiveto the webs and the strips, as they travel in spaced apart relation tothe combining location, adhesively to secure together the strips andwebs in such manner that the strips form a gusset joining the webs,segmenting the resultant composite gusseted structure to form individualcover lengths, and seaming each cover length along its two sidestransverse to the gusset.

6. The method of making paper covers particularly for use to coverrelatively large objects, such as large articles of furniture,comprising the steps of withdrawing two relatively wide continuous websof paper from individual supplies thereof and causing them to travel insuperposed and aligned but spaced apart relation to a comining locationwhere they come together, withdrawing two paper strips of the same widthand narrower than the webs from individual supplies thereof and causingthem to travel between the webs in superposed and aligned spacedrelation with respect to one another, said strips coming together withone another and with said webs at said combining location with theinnermost edges of the strips aligned with one another and also with theoutermost edges of the strips aligned with one another and with twoaligned edges of the webs, applying adhesive to the webs and the strips,as they travel in spaced apart relation to the combining location,adhesively to secure the strips together flatwise at their inner marginsand adhesively to secure the outer mar gin of one strip flatwise to theouter margin of the adjacent web and the outer margin of the other stripflatwise to the outer margin of the other web in such manner that thestrips form a two-panel gusset joining the webs, segmenting theresultant composite gusseted structure to form individual cover lengths,and seaming each cover length along its two sides transverse to theusset.

7. The method of making paper covers particularly for use to coverrelatively large objects,
